Chrysler NSG370 transmission

The Chrysler NSG370 is a six-speed overdrive manual transmission sourced from Mercedes. It is Jeep's first six-speed manual transmission and Chrysler's second after the Dodge Viper T-56.

The NSG370 does not use standard gear oil for lubrication. It uses a 10W30 or automatic transmission fluid weight manual transmission fluid. Common synthetic alternatives to the factory Mopar-branded conventional lubricant are Royal Purple's Synchromax and Red Line Oil's MTL. The synthetic alternatives often improve shifting performance while decreasing internal wear and noise.

Only a fluid characterized by the MS-9224 specification should be used in order to avoid voiding the factory warranty.

It features a 14mm hex fill plug on the passenger side and a 17mm hex drain plug on the bottom (with a strong magnet for attracting metal flakes).

Gear ratios:

1	2	3	4	5	6	R
